C # tuples Pair Triplet Tuple

C # The Pair, Triplet, and Tuple (New in 4.0) tuples are provided by default. When using some small data structures, we do not need to declare the corresponding data structures, replace them with these tuples.

The above two items are serializable objects that represent two or three attributes. However, you must note that all their attributes are objects, and the namespace is System. Web. UI, that is, they are in System. Web. dll.

In. In net4.0, C # adds a Tuple that can represent 1-8 strongly-typed attributes, which is in the System namespace of mscorlib. dll.

The Tuple <...> all have the [Serializable] attribute to indicate that it can be serialized. It can be seen that Tuple is just a simple factory. You can use it to create Tuple <...> type objects.
